Fluid intelligence is the type of intelligence that has to do withshort-term memory and the ability to think quickly, logically, and abstractly inorder to solve new problems. It 1 in young adulthood, levels out for a period oftime, and then 2 starts to slowly decline as we age. But3aging is inevitable,scientists are finding that certain changes in brain function may not be.
One study found that muscle loss and the4of body fat around the abdomen areassociated with a decline in fluid intelligence. This suggests the5thatlifestyle factors might help prevent or6this type of decline.
The researchers looked at data that7measurements of lean muscle andabdominal fat from more than 4,000 middle-to-older-aged men and
women and 8 thatdata to reported changes in fluid intelligence over a six-year period. Theyfound that middle-aged people 9 higher measures of abdominal fat10 worse onmeasures of fluid intelligence as the years11.
For women, the association may be12to changes in immunity that resultedfrom excess abdominal fat; in men, the immune system did not appear to be13. Itis hoped that future studies could14these differences and perhaps lead todifferent 15 for men and women.

解析：
1. 文章开篇提及，液态智力指的是一种与短期记忆有关的智力，以及为了解决新问题而进行快速、逻辑思维和抽象思维的能力。第一空前的代词it指代的正是液态智力(Fluid intelligence)，此时结合后文levels out for a period of time(稳定一段时间)和 andthen starts to decline(紧接着开始回落), 可以得知，液态智力先向上达到峰值，然后逐渐回落，所以，C选项peaks：达到峰值符合题意
2. 此空格考察副词，修饰动词starts，纵观四个选项，alternatively adv.要不，或者;非此即彼;二者择一地;作为一种选择。formally 正式地，accidentally adv. 意外地;偶然地 generally adv.通常;普遍地，一般地可以得知，generally adv. 通常;普遍地，一般地符合题意
3. 此处考察逻辑关系，不难发现，aging is inevitable和后文中科学家的结论certain changes in brainfunction may not be，意义相反，故while 尽管虽然符合题意
4. 此空格依旧考察逻辑关系识别，muscle loss(肌肉的消失)与____ of body fat (体内脂肪)为并列关系，所以，accumulation 积累，堆积，符合题意
5. 此空后方为that同位语从句根据同位语从句中提到的lifestyle factors mighthelp，其中，might为推断。可以得知，possibility 可能性符合题意。
6. 此空再次考察逻辑关系 or，结合前后语境，lifestyle factors might help prevent 或者___type ofdecline. 第6空为前方prevent同义词，故delay 延迟符合题意
7. 此空位于先行词为data的定语从句中,建立data与measurements之间主谓关系之后，不难发现，应填入“关于腹部脂肪测量的数据”，即，数据包括了腹部脂肪测量，句意为：研究人员查看了4000多名中老年男性和女性的肌肉和腹部脂肪测量数据，included符合题意
8. 此空在考察逻辑关系，动词词义辨析的同时，又考察了介词搭配。基于后文介词to,和整句句意：研究人员查看了4000多名中老年男性和女性的瘦肌肉和腹部脂肪测量数据，并将这些数据与六年时间内报告的液态智力变化进行了比较。不难发现，compared符合题意。
9. 此空格考察介词用法，基于middle-aged people 和higher measures of abdominalfat关系为：腹部脂肪含量较高的中年人，不难发现， with prep.具有，带有，符合题意
10. 基于此空所在句含义，同时，结合本段背景信息“在一项研究中，”只有 scored得分符合题意，且score可以搭配worse，表示，得分更低。句意：他们发现，腹部脂肪含量较高的中年人在液态智力测试中的得分越来越低，
11. 此空考察动词词组辨析，run out 用完，耗尽，set off 启程，出发，引爆(炸弹)，draw in (天黑)渐早;(白昼)渐短 goby (时间) 流逝。as years went by 时光飞逝，故 went by符合题意，整句句意：他们发现，随着时间的推移，腹部脂肪含量较高的中年人在液态智力测试中的得分越来越低。
12. 此空看似考察形容词辨析，实则再次考察逻辑关系，上文提到的腹部脂肪含量高与液态智力测试中的得分之间的关系(theassociation)与后文免疫力变化(changes in immunity)为因果关系，故 attributable符合题意。整句句意：对妇女来说，这种联系可能是由于腹部脂肪过多导致的免疫力变化;
13. 此空考察动词词意辨析，句意为：在男性中，免疫系统似乎没有参与其中。involved adj.有关的，涉及的，卷入的符合题意。
14. 此空考察动词辨析，基于主语future studies和宾语these differences之间的关系，可以确定， explainvt.解释符合题意，句意：希望未来的研究能够解释这些差异。
15. 此空考察逻辑关系和名词词意辨析。既然是大众希望，未来研究领航，此处应该希望研制出治疗措施，故treatment n.治疗，疗法，符合题意。整句句意：人们希望未来的研究能够解释这些差异，并可能导致对男性和女性的不同治疗。
16. 此空考察逻辑关系，基于上下文都在探讨寻找疗法和措施，态度趋同，meanwhileadv.与此同时符合题意
17. 此空考察搭配 takesteps采取一些措施,句意：同时，随着年龄的增长，你可以采取一些措施来帮助减少腹部脂肪和保持肌肉。故take采取符合题意。
18. 此空考察名词词义辨析，你可以采取一些措施来帮助减少腹部脂肪和保持肌肉，以保护你的身心健康。wellbeing n.幸福，健康，安乐符合题意
19. 此空考察名词词义辨析,基于前方increase和后方aerobic exercise(有氧运动)，应该填入 level n.水平。句意：强烈推荐的两种生活方式是:保持或增加有氧运动水平.
20. 此空考察名词词义辨析,基于high in fiber，可以得知 dietadj.日常饮食，规定饮食符合题意。句意：遵循高纤维、不吃深加工食品的地中海式饮食。
